Nissh

A numbered, made-to-order 3D-printed gaming mouse, shaped to the buyer's hand in a browser configurator.

The One Builder configurator on nissh.gg: on the left the quick-start hand sizes, the gamer tag field, the hump choice Fingertip, Eclipse Mini or Eclipse and the side-button switch; on the right the 3D preview of the black lattice-shell mouse on a grid, the white collector card numbered 12 standing behind it, and the Full Build and Mod-Kit badges reading Restocking.
The configurator: contours on sliders, the shell previewed live, the numbered card behind it.

Nissh One is a gaming mouse shaped to one hand: the buyer sets the hump and the finger contours on sliders in a browser 3D configurator, approves the render and pays by card. On the server a parametric CAD pipeline turns that configuration into print-ready files in minutes; the shell is printed in-house in Hungary and numbered, and most builds come in well under 50 g. Product, industrial design, web, CAD and shop were built and are run by one person; the site has been public since August 2025 and orders opened in April 2026.

Main functions

  • Browser 3D configurator: the hump, the thumb, ring and pinky contours and the two click surfaces on sliders in 0.1 mm steps, previewed live in React Three Fiber; a configuration is saved and shared by URL.
  • Server-side parametric CAD on replicad and OpenCascade: a configuration becomes print-ready STL files in minutes, the whole mouse and the numbered collector card with the gamer tag.
  • A server-side constraint engine: a configuration outside the allowed bands is refused at checkout, and the buyer approves the exact 3D render before anything is printed.
  • Numbered, made-to-order units: each paid order gets its edition number, with Stripe checkout, szamlazz.hu e-invoicing reported to the Hungarian tax authority, status emails and an order page with tracking.
  • FedEx shipping from Hungary to 27 EU countries and the US, at a fixed rate per country.
  • Bespoke builds by numbered quote past the slider limits, and re-shell orders for existing owners, unlocked with the order code and the edition number.
  • An admin back office: orders, bespoke quotes, pay links, FIFO inventory with the buildable count derived from the bill of materials, and the true margin per order after card fees, labour and shipping.
  • A mouse sensitivity converter across 322 games at sens.nissh.gg, with cm/360 and arbitrary-precision math.

The nissh.gg home page: a greyscale hand reaching down from the top right, the headline Built for your hand, not the average hand, a line about a competitive mouse cast in deep black resin, shaped to your hand and numbered once, the Build yours and Learn more buttons, and the black lattice-shell mouse below.

The configurator on a phone: the One Builder header with Save and share, a notice The builder ends here about maxing out the ring finger's side reach with a Talk to Nissh link, the heading Make it yours, the 3D preview with the numbered card and the mouse on a grid, a compare field for a config code, the quick-start hand sizes, the gamer tag section and a Review and order bar at the bottom.

The anatomy section of the home page in exploded view: the lattice shell floats apart from the base, the thumb, ring and pinky contour pieces glow violet, and a card titled Finger contours reads Your fingers land where they land, each contour placed from your measurements, not a factory average.
The anatomy story: the three finger contours that the sliders move.
The Lights out, game on section: the glow-in-the-dark lattice shell glowing green against a dark background, under it the line Glow-in-dark ABS, hand-finished to perfection, your One stands out even when the lights go down, and a Build yours button.

The Bespoke page: the badge Nissh One Bespoke, Numbered, 1 of 1, the eyebrow Beyond the builder, the three-line headline starting One mouse. Your number., a paragraph on designing it together and shipping it numbered, the counters 1 hand shaped and No. 002 next, a Start the conversation button for Discord, and on the right the violet collector card numbered 002 and marked Bespoke.
Bespoke: a 1-of-1 build by quote, past the slider limits.
